Description
Technical field
What the present invention relates to is a kind of special long shaft underwater halogen transmitting pump, is used for the special bittern of carrying on China's western salt lake development technology flow process, belongs to halogen pump technical field.
Background technique
At present, area, domestic western salt lake is gathered and is carried bittern, because bittern is than great, and the concentration height; in course of conveying, have crystalline particle and separate out, its crystalline particle can be adsorbed on the impeller blade surface, the pump runner; conveying pipeline inner walls etc. are located, and, can be deposited on the bottom, priming reservoir equally.So, just be faced with following problem in the bittern transfer pump using process:
1), the crystalline particle adsorption rate on impeller blade surface and the runner inner wall is quite fast, impeller channel will soon be stopped up, must clear up;
2), there are the problems referred to above too in the crystalline solid on the inner-walls of duct;
3), in the priming reservoir because the deposition of crystalline particle, raise gradually at the bottom of can making the pond, need regularly clear up;
More than three problems have all a common ground is exactly how to prevent crystallization and how to clear up crystallization.The problems referred to above all need to dismantle pump foundation when the cleaning crystallization, pipeline, and when the cleaning depositing crystalline, relatively more difficult.Because crystallization speed is quite fast, general tens hours, even have only several hours and the pump inner flow passage will be stopped up, like this, cleaning crystallization meeting becomes quite frequent, and the process of cleaning crystallization itself also needs the suitable time, like this, can have a strong impact on the conveying of bittern, make manufacturing efficiency quite low.
Summary of the invention
The present invention proposes a kind of special long shaft underwater halogen transmitting pump, is intended to overcome the above-mentioned defective of existing in prior technology, have simple in structure, reliable, and characteristics such as anti-salt crust and easy cleaning saline crystallization body.
Technical solution of the present invention: its structure is that grease chamber, motor cabinet, support column, support, support column are housed on the floor, self-aligning thrust roller bearing and selfaligning roller bearing are contained in the grease chamber, self-aligning thrust roller bearing, selfaligning roller bearing and guide bearing supporting spindle, impeller, impeller nut and drainage cap are housed on the main shaft, the pump housing and rear pump cover are fixed on the support column, import pipe box, inlet tube are contained on the pump housing, and fixed plate is the pump housing fixedly.Gap S between impeller and the inlet tube is 3～20mm; Arrange a plurality of spray-holes on inlet tube, this aperture is 2～5mm.
Bittern transfer pump adopts the pattern under the major axis liquid, and whole pump is vertical mounting type, is installed on the basis by the floor, and impeller, the pump housing are immersed under the bittern.
Advantage of the present invention: package unit has the perfect measure of bittern at the pump intercrystalline that prevent, has prolonged the time of pump intercrystalline greatly, for the conveying of technological process bittern provides sound assurance.Because adopt the pattern under the major axis liquid, whole pump weight is lighter, when stopping up appears in the pump internal crystallization, pump integral body can be hung out, put into fresh-water pool and soak, make the crystallization adhesive layer dissolving in the pump runner, and then return, whole process is simple to operation; Or adopt and in support column, introduce pressure fresh water with bittern extrusion in the pump, and stir the method for eliminating the pump intercrystalline by the motor reduction of speed, and simple and reliable, save the human and material resources resource greatly.Adopt structural type under the major axis liquid, installation process is simple, fast, and the Location accuracy height is guaranteed the working environment of special long shaft underwater halogen transmitting pump, significantly reduces the vibration and the noise of pump, guarantees the reliable operation of pump.
